The Division of Drug Marketing, Advertising, and Communications
(DDMAC) of the U.S. Food and Drug Administration (FDA) has reviewed a professional detail aid
(detail aid) (NU0359) for Nasonex (mometasone furoate monohydrate) Nasal Spray, 50 mcg (Nasonex)
submitted by Schering Corporation (Schering) under cover of Form FDA-2253. This detail
aid is false or misleading because it claims that Nasonex is more effective than has been demonstrated
by substantial evidence or substantial clinical experience and makes unsubstantiated
superiority claims for Nasonex. The detail aid therefore misbrands the drug in violation of the Federal Food,
Drug and Cosmetic Act (Act). 21 U.S.C. 352(a) and 321(n); cf. 21 CFR 202.1(e)(6)(ii).

Background
According to the FDA-approved product labeling (PI), Nasonex is
indicated for the following:
â€¢ The treatment of the nasal symptoms of seasonal allergic and
perennial allergic rhinitis, in adults and pediatric patients 2 years of age and older.
â€¢ The prophylaxis of the nasal symptoms of seasonal allergic
rhinitis in adult and adolescent patients 12 years and older. In patients with a known seasonal
allergen that precipitates nasal symptoms of seasonal allergic rhinitis, initiation of prophylaxis
with Nasonex is recommended 2 to 4 weeks prior to the anticipated start of pollen season.
â€¢ The treatment of nasal polyps in patients 18 years of age
and older.

Safety and effectiveness of Nasonex have not been established in
pediatric patients less than 2 years of age for the treatment of the nasal symptoms of seasonal and
perennial allergic rhinitis, and in pediatric patients less than 18 years of age for the treatment of nasal
polyps.

The Clinical Studies section of the Nasonex PI discusses trials
performed in patients with allergic rhinitis (in pertinent part):

Allergic Rhinitis
The efficacy and safety of NASONEX Nasal Spray, 50 mcg in the
prophylaxis and treatment of seasonal allergic rhinitis and the treatment of perennial allergic
rhinitis have been evaluated in 18 controlled trials, and one uncontrolled clinical trial, in
approximately 3000 adults (ages 17 to 85 years) and adolescents (ages 12 to 16 years). These
trials evaluated the total nasal symptom scores that included stuffiness, rhinorrhea, itching, and
sneezing. Patients treated with NASONEX Nasal Spray, 50 mcg, 200 mcg/day had a significant
decrease in total nasal symptom scores compared to placebo-treated patients.

The efficacy and safety of NASONEX Nasal Spray, 50 mcg in the
treatment of seasonal allergic and perennial allergic rhinitis in pediatric patients
(ages 3 to 11 years) have been evaluated in four controlled trials. Pediatric patients
treated with NASONEX Nasal Spray, 50 mcg (100 mcg total daily dose, 347 patients) had a significant
decrease in total nasal symptom (congestion, rhinorrhea, itching, and sneezing) scores, compared to
placebo-treated patients.

Prophylaxis of seasonal allergic rhinitis for patients 12 years of
age and older with NASONEX Nasal Spray, 50 mcg given at a dose of 200 mcg/day, was evaluated
in two clinical studies in 284 patients. Patients receiving 2 to 4 weeks of prophylaxis
with NASONEX Nasal Spray, 50 mcg demonstrated a statistically significantly smaller mean
increase in total nasal symptom scores with onset of the pollen season as compared to placebo
patients.

Overstatement of Efficacy
As demonstrated by multiple prominent references to the term
"congestion" (highlighted by large type, colored text, and bolding) and the presentation of data related to
congestion alone, the detail aid repeatedly states or suggests that Nasonex is effective in the
treatment of the specific symptom of nasal congestion, when this has not been demonstrated by substantial
evidence or substantial clinical experience. For example, page one of the Nasonex detail aid
contains the headline claim, "Nasal allergy sufferers report Congestion at night can be a BIG
problem" (original emphasis). To the right of the detail aid is a tab that asks, "How BIG?"
When the tab is pulled, the following claims appear:
â€¢ In a nasal allergy survey 1 48% of respondents reported difficulty falling asleep due to
congestion, 51% said that congestion woke them up
â€¢ Congestion during the day can also be a BIG problem for
sufferers
In the same survey 59% of adults reported that they were affected at work. (original
emphasis)

Pages two and three of the Nasonex detail aid contain the headline, "NASONEX for BIG CONGESTION RELIEF night and dayâ€¦" (original emphasis)
along with the claim, "TREATSâ€¦BIG reduction in congestion sustained throughout a 90-day study2" with a presentation of mean percentage decrease in AM/PM diary symptom
scores for total nasal symptom scores and congestion scores at days 0, 1-15, 16-30, 31-45, 46-60, 61-75, and 76-90 in patients with moderate-to-severe perennial allergic rhinitis treated with Nasonex, Flonase (fluticasone propionate), or placebo. Accompanying this presentation and throughout the
Nasonex detail aid is the tagline "BIG congestion relief" (original emphasis). The back cover of the
Nasonex detail aid includes the claim "â€¦the only nasal-inhaled steroid that's also FDA approved to
help PREVENT congestion" (original emphasis).

Page four of the Nasonex detail aid includes the claim,
"Allergists and ENTs prescribe for tough-to treat congestion â€“ NASONEX continues to be their #1 new
Rxâ€¦."

Nasonex, however, is not specifically indicated for congestion. As
discussed above, it is indicated, in part, for the prophylaxis and treatment of seasonal allergic
rhinitis (SAR). The SAR indication is based upon the results of clinical trials in which the primary
efficacy endpoint was measured by the total nasal symptoms score (TNSS) which included four symptoms: congestion, rhinorrhea, itching,and sneezing, as opposed to results with respect to individual
nasal symptoms such as nasal congestion. These studies did not specifically evaluate efficacy
for the stand-alone symptom of nasal congestion. Consequently, they are not considered substantial
evidence to support a claim of efficacy for nasal congestion.

There are two references cited to support the claims above. One of
the references cited1 is an online survey sponsored by Schering regarding nasal congestion in allergic
rhinitis patients. This survey, however, does not provide substantial evidence to support claims
that Nasonex treats the specific symptom of nasal congestion in allergic rhinitis patients because,
as a general matter, surveys alone cannot support claims of efficacy. The other reference cited2 also
does not provide substantial evidence to support claims that Nasonex treats the specific symptom
of nasal congestion in allergic rhinitis patients. The primary efficacy variable in the referenced
study was the TNSS, not nasal congestion. TNSS is a composite measure of symptoms. Demonstrating
an effect on a composite multiple symptom measure of the TNSS does not represent a clear
effect on any individual component of the TNSS. Absent substantial evidence or substantial clinical
experience demonstrating Nasonex's effect on the particular component symptom, making a claim related
only to the component symptom of the TNSS overstates Nasonex's efficacy. FDA is not aware of any
substantial evidence or substantial clinical experience demonstrating that Nasonex
specifically treats nasal congestion. If you have additional data to support such claims, please submit them to
us for review.

Page five also includes the following claim:
"Based on scent and taste attributes in a headto-head preference study3 Patient-preferred 2 to 1 versus
Flonase" along with a graph entitled, "Patients Preferred NASONEX versus Flonase,"
which shows the percentage of subjects who preferred Nasonex to Flonase with respect to the following sensory
attributes: (1) scent/odor; (2) immediate taste; and (3) aftertaste. These claims and presentations
are misleading because they imply that patients prefer Nasonex to Flonase based on all of the
attributes assessed in the "preference study" and that patients prefer Nasonex to Flonase overall, when this has
not been demonstrated.
The support for the claims of patient preference for Nasonex to
Flonase with respect to sensory attributes and overall patient preference is subject responses to
an "overall product preference" questionnaire.3 The claim of "overall patient
preference" for Nasonex is misleading because it is
based on patient responses to a single question in the "overall
preference questionnaire" that assessed eight product sensory attributes ("Based on these attributes which
product do you prefer overall?"). The use of responses to this single question is not sufficient to support
the broad concept of overall patient preference because patient preference cannot be adequately measured
by a single item in an instrument. Patient preference encompasses multiple aspects of
patient experiences such as convenience, ease of use, dosing, dosage form, all aspects of
efficacy, and adverse events.

Additionally, patient preference is influenced by more than just
sensory attributes of a drug. Further, it is unknown whether the eight sensory drug attributes cited in the
reference3 are the most concerning and relevant to patients taking nasal steroids. Patient preference
claims should be well-designed and controlled head-to-head studies using well-developed instruments
that can evaluate patient preference. Thus, the reference cited to in the detail aid is not sufficient to
support these claims. Moreover, your presentation is misleading because the prominent
graph on page five of the detail aid selectively presents from the questionnaire only results favorable
to Nasonex. In fact, the questionnaire contained eight questions about specific sensory
attributes of Nasonex and Flonase, and Nasonex received significantly better scores than Flonase for only
half of these questions. While the graph prominently presents the data for three of the attributes
where Nasonex scored better than Flonase and is headlined by a claim indicating that patients prefer
Nasonex "2 to 1" to Flonase, it misleadingly omits the results from the other sensory attribute
questions where Nasonex did not score significantly better than Flonase. While we note that a footnote to
the graph lists the eight sensory attributes measured in the questionnaire, this disclosure is not
sufficient to mitigate the selective and misleading presentation in the graph.

Conclusion and Requested Action
For the reasons stated above, the detail aid is misleading and
therefore, it misbrands your drug in violation of the Act, 21 U.S.C. 352(a) and 321(n). Cf. 21 CFR.
202.1(e)(6)(ii).
